IMPROVEMENT IN STAMP-CANCELERS.

Specification forming part of Letters Patent No. 133,435, dated November 26, 1872.

To all whom it may concern: y

Beit known that I, JOHN GoLDsBoRoUGH,

of Philadelphia, Pennsylvania, have invented an Improved Stamp- Canceler, of which the following is a specilication:

My invention relates to stamp-canceling machines having resp-like plates, which tear the stamps; `and my invention consists in pro` riding each serrated plate with a projection at the side, upon which a sliding handle bears directly, so that the plate is turned when the handle is depressed. By this arrangement the full force ot' the blow upon the handle is transferred without loss to the serrated plate, while there is a great gain in simplicity ot' construction, strength, and durability over maslide arms k L projecting from the lower end of the handle A and between the disks. A pin, j, at the inner side ofthe disk g, extends into a slot in the arm k, and a pin, j', on the disk g1, into a slot in the arm 7c', so that when the handle is raised or depressed the disks will be turned simultaneously in opposite directions.

Therasping-edges oftheplatesbeingbrought against the face. of a stamp, a smart blow on the end of the handle A, depressing the same,

will rotate the plates, and cause the scraping away of parts of the stamp, the spring b raising the handle, and restoring the plates to their tirst position on removing the pressure.

Claim.

The combination of the sliding handle A, rotating serrated plates g1 g2, projections j j', and recesses in the handle receiving said projections, all operating as set forth.

In testimony whereof I have signed my name to this specification in the presence` of two subscribin g witnesses.

JOHN GOLDSBOROUGH.
